- This invention relates to oil burners and more particularly to crude oil burners.

A primary object of the invention is to provide an oil burner utilizing steam as an 3 atomizer and which is so constructed that it may be used in any type of boiler furnace and throw a fan-shaped smokeless flame which is produced with a minimum amount of noise and which will successfully burn 1 either heavy or light grade crude oil.

Another object is to so construct a burner of this character that it may be regulated to produce either an extremely low fire or a welding hot one, which is easy to light and when lit remains so. 7

Another object is to provide a crude oil burner constructed so as to avoid clogging with trash or sediment; which is quiet, economical and efficient and which will lift any oil which will flow through the suction pipe.

In carrying out these objects, the invention is susceptible of modification without departing from the spirit or sacrificing any of the advantages ofthe claimed invention; there being shown in the drawing for illustrative purposes a preferred and practical form, in which:-

Figure 1 represents a longitudinal section of a burner constructed in accordance with this invention,

Fig. 2 is a similar view taken in a plane at right angles to Fig. 1, Fig. 3 is a front elevation thereof, and Fig. 4 is a transverse section taken on the line 4.4; of Fig. 1. i

In the embodiment illustrated the burner constituting this invention which may be used in furnaces of steam boilers, of either marine or stationary type, comprises a body 1 in the form of a casting of brass, steel or cast iron, and a tip member 10 preferably of brass, and detachably connected with the body. The body 1 has a chamber 2 formed therein, the rear wall of which is tapped and threaded as shown at 3 to receive the steam supply pipe S through which steam enters a ment wlth the rear wall of the body 1 and which communicates with the steam supply pipe S. This jet 20 extends longitudinally ]et or nozzle 20 having a threaded engage-' through the body 1 into the tip member 10 terminating in a flat nozzle 21 disposed slightly in rear of the nozzle 11 of the tip member 10 and in longitudinal alinement therewith, it being spaced about one inch from said tip nozzle. Both of these nozzles or mouths are flattened out and constructed to throw a fan-shaped spray which is ac complished by constricting the lips of the mouth of each nozzle at the center so that the lips approach closer to each other at this point but are still separated and then'grad ually separate toward the ends or sides of the mouth. As shown in Fig.2 these lips are made convex or curved longitudinally outward with the corners spaced backward some distance from the centers of the lips.

An oil supply reservoir R is provided below the level of the mouth of the nozzle 11 and contains oil under atmosphericpressure. An oil supply pipe]? leads from said oil supplyand enters the chamber 2 of the body 1 at the rear thereof at a point below the steam pipe S, the chamber 2 and tip member 10' combining to form an oil chamber into which oil is drawn by the vacuum produced in said chamber incident to thedischarge of steam from the nozzle 21 through the nozzle 11.

The tip member 10 maybe of any desired length, preferably about six inches, and has its rear end threaded for threaded engagement with the front end of the body 1, and is divided adjacent said threaded portion with an annular collar' or shoulder 12 which abuts the front end of the body 1 when the tip is screwed into opposite position. The front end of the tip 10 is flattened and constructed to throw the oil in a fan-shaped spray which is accomplished by constricting the lips of the mouth at the center thereof to about of an inch in width or rather the distance between said lips being this wide and then gradually separating them up to of an inch at the sides, the mouth being about 1% inches across the top. The mouth 21 of the jet 20 extends to about within one inch of the mouth of the tip so that the steam flowing at a high velocity through said jet will meet the oil at this point and break it up into a very fine mist and force it out of the mouth of the tip in a fan-shaped spray at an angle of degrees horizontally, thereby forming a vacuum in the chamber 2 of the body. This vacuum formed in the chamher 2 inconnection with the atmospheric pressure behind the oil operates to force the oil through thepipe P which iscaught in the flow of steam at the opening of the steam jet and broken up into a very finevmistor spray and forced out of themouth of the tip member at a high velocity in a fan-shaped spray and when ignited will fill the furnace with a clear fire, without smoke, and which is comparatively noiseless.

to the shape and form of the jet so blown it readily mixes with the air resulting in a more'economical consumption of fuel.

' The flame so formed has raised from a very small diameter to one of enormous proportion which results in a greater amount of heat with the less fuel.

It is,,of course, understood that the burner may be made in various sizes depending upon the use for which it is required, and, of

the-burner, a 1%'IlIlCl1 needle valve being.

' claimed. r

course, suitable valves are provided-for controlling the steam and oil passing through preferably provided for the oil and a 1% .inch globe orlangle for the steam atomizer.

By properly operating the valves controlling the steam-jet and the oil supply pipe a very slow fire may be had which is very desirable when-raising steam on a cold boiler or the fiame'may be so controlled asto produce a welding-hot fire without any smoke.-

" This burner will lift oil from an under ground tank without any trouble providing the oil will'flow through the suction pipe P. -This burner may be used either with or without an oil pump and when a pump is used it is advisable to have a constant pres sure. 7

Without further description, it is thought that the features and advantages of the inl vention will be readily apparent to thoseskilled in the art, and it will of'course be understood that changes in the formfproportion and minor details of construction may be resorted to, without departing from the spirit of the I claim 1.
